CRICKETS. 



23 



Species of Gryllotalpa are found in Europe (including England), 

 Asia, Africa and Australia. Cylindrodes is found in Australia, and 

 is said to live in the stems of a plant. It is quite smooth and of a 

 yellowish colour. 



A remarkable insect of this family is Tridactyla, a genus found 

 in Europe, India, Africa and America. The hind tarsus is absent, 

 and in its place are four curiously-formed spurs, which are hooked

Rhipipteryx limbatus, enlarged three times. (1203.) 



and toothed at the end ; one of these is directed upwards and 

 inwards. A closely allied insect is Rhipipteryx (fig. 21, 1203). 

 This has only ten joints to the antennae, which in the Gryllidce, are 

 usually very long and slender, and the wings are unlike those of any 

 other insect. The front margin is leathery ; the rest of the wing is 

 fan-like, entirely without cross nervures, and when at rest is folded 

 under the leathery front margin. 



Family Phasgonueid^e. 



The Long-horned Locusts, Phasgonuridce (1 241 -1 254), differ from Table- 

 the Gryllidw in having four joints to their tarsi. The first three joints 

 are of about equal length, furnished beneath with soft fleshy pads 

 which enable them to hold on to leaves and stems of plants. The 

 antennas are of great length and very slender, consisting of a 

 large number of joints ; 480 have been counted in the antennae 

 of lleroncidius.
